Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a bushing block obtained by using a material substituted for electrocast brick or the like, having small wear due to molten glass and capable of being stably supplied and also solving a problem of reduction in the temperature of the passing molten glass. SOLUTION: The bushing block is obtained by forming the sintered brick to a prescribed shape and thermally spraying platinum on the inner surface by flame spraying method. The thickness of the platinum coating film is controlled to 250 μm (a). In addition, the platinum coating film is partially formed on the front surface and the rear surface alternately which are used as electrodes for electric heating (b). COPYRIGHT: (C)2008,JPO&INPIT
